Answer:
3.33
Step-by-step explanation:
Independent events:
If two events, A and B, are independent, we have that:
In this question, we have that:
The question are independent of each other.
Event A: Correct guess on the first question.
Event B: Correct guess on the second question.
A quick quiz consists of a multiple-choice question with 6 possible answers followed by a multiple-choice question with 5 possible answers.
This means that
Probability that both responses are correct.
The answer is 3.33%. Since it asks without the "%" symbol, 3.33
Answer: Company A is charging $13 per pound of chocolate

Answer:
s = 12
Step-by-step explanation:
Corresponding sides of similar triangles are proportional. For similar triangles ABC and XYZ, pairs of corresponding sides are ...
AB and XY . . . . 6 and 9
BC and YZ . . . . not given
CA and ZX . . . . 8 and S
__
We can write the statement of proportionality four (4) different ways. For purposes of finding the unknown S, it is convenient to choose an equation that has S in the numerator:
ZX/CA = XY/AB
S/8 = 9/6
Multiplying by 8 gives the value of S:
S = 8(9/6)
S = 12
_____
<em>Additional comment</em>
Other ways we could write the statement of proportionality are ...
CA/ZX = AB/XY ⇔ 8/S = 6/9
ZX/XY = CA/AB ⇔ S/9 = 8/6
XY/ZX = AB/CA ⇔ 9/S = 6/8
The 15 pound of cat food because if you divide 15.30 by 15 it gives you 1.02 which is the price per pound.
For the dog food you would divide 12.36 by 12 to get 1.3.
The price per pound for the cat food is cheeper the the dog food which means you get more food at a lower cost.
Hope this helps!
